Original GitHub issue: https://github.com/RVC-Project/Retrieval-based-Voice-Conversion-WebUI/issues/1981

I had no problems during training, and successfully found the model I wanted in the timbre options. However, when I selected the output audio, the following error occurred(我在训练中没有出现问题，也成功的在音色选项中找到了我要的模型，然而选择输出音频时出现了以下报错)：
